I'm thinking about starting the first exchange that uses blackcoin as the primary coin of exchange. The code I have been working on would be similar to mintpal.

For example we would have:
BC <-> BTC
BC <-> LTC
BC <-> PPC
BC <-> DOGE
etc...

This would allow multipool exchange operators to directly exchange into blackcoin making it cheaper and easier for everyone. We could even do trading discounts on targeted currencies.  

How much interest is there in this idea? I love the idea of a blackhole currency that absorbs weaker altcoins.
